Part number is EK-U1-ZCU104-G
Product Question: The question i am using zcu104 fpga board .Now on that fpga board DS8 led is not glowing and in Quick start guide it is mentioned that the DS8 led will not glow .DS8 led is VADJ now i want to know to how to configure that how to glow that DS8 Led .How to set the Vadj Voltage is there any jumper settings or from any software do we have to use to make it glow .Tell me how to configure the Vadj and one more thing on the zcu104 board there is jumper there J178 if you search in amd user guide you might not able see check in infineon user guide there you will see Vadj_fmc Pin header how to configure that what is the purpose of that pinheader .In user guide it is mentioned that the ZCU104 board is supplied with 1.8v Vadj_fmc so tell me how to check that because there is testpoint and using multimeter i have checked no voltage is there .Please tell me the solution how to set that.Beacuse of Vadj Voltage i am not able to use xm105 fmc debug card with my ZCU104 Board.
Hello @asgar.reza,
Here is what I see:
- VADJ_FMC_PGOOD is an open drain output from the Infineon IRPS5401MTRPBF indicating that “Switcher D is powered up”
- Switcher D (VADJ_FMC) is configured to provide less than 2.55 VDC as there is no voltage divider for the feedback signal.
- a 10 kΩ is provided by resistor RP1
- DS8 is driven by the SN74AVC8T245
- The VADJ_FMC_PGOOD is sent to the FMC connector pin PG-C2M
- The FMC XM105 debug card includes a MOSFET to drive LED DS5 when the VADJ_FMC_PGOOD is valid. Again, we note that the pull up resistor on the EK-U1-ZCU104-G is an essential component to activate DS5.
Returning back to the FPGA board, J178 is “Switcher C enable input control”. Note that Switcher C is associated with the 5.0 VDC supply.
The IRPS5401 has programmable output voltages with ranges from 0.25 to 2.55 (without voltage divider). The regulator may be programmed via the ZCU104’s J175 header.
I suspect you will need to program the regulator to obtain the desired voltage for your FMC card. This is the appliable material from the user’s guide:
Voltage and current monitoring and control are available on the power rails provided by the
Infineon IRPS5401 power controllers through the Infineon IR PowERCenter graphical user
interface. The onboard Infineon IRPS5401 power controllers listed in Table 3-31 are
accessed through the I2C 1x3 male pin connector J175, which is included with the Infineon
USB cable (Infineon part number USB005). The cable can be ordered from the Infineon
website [Ref 22]). The associated Infineon IR PowERCenter GUI can be downloaded from the Infineon website. This is the most convenient way to monitor the voltage and current values for the Infineon PMBus programmed power rails listed in Table 3-31.
Sincerely,
Aaron
